DNA is double stranded helix, connected by what could be described as "ladder rungs". These rungs are actually nucleotides, the

building blocks of DNA. A sequence of three of these nucleotides is known as a codon. Codons are important in the composition of proteins, because each codon calls for a specific

the codon calls for a specific amino acid

Answer:

Codons are important in the composition of proteins, because each codon calls for a specific amino acid.

Explanation:

The genetic message contained in the DNA is formed by an alphabet of four letters that correspond to the four nucleotides: A, T, C and G.

With these four letters it is necessary to form "words" that have the meaning of "amino acids".

The genetic code of DNA is expressed by broken bases, which were called codons. Each codon, formed by three letters, corresponds to a certain amino acid.

The correspondence between the trio of bases of DNA, the trio of bases of RNA and the amino acids specified by them constitutes a message in code that came to be known as "genetic code".

Which normal cell characteristic is represented by the production of insulin in the beta cells of the pancreas? Select one: a. C
pychu [463]
Insulin is produced by beta cells of the pancreas for storing and disposing of the glucose in various parts of the body like liver. This activity is a differentiated function of the beta cells of pancreas only. Although gene for insulin production is present in all cells, it is expressed only in the beta cells. Hence, it is a differentiated function.

Different microbes grow in a wide variety of environmental conditions; however, most have preferences for certain temperatures,
lesya692 [45]

Answer:

this is a TRUE statement.

Explanation:

Different microbes grow in a wide variety of environmental conditions; however, most have preferences for certain temperatures, pH, and atmospheric gases because although microbes are widespread in their occurrence,they are found almost everywhere,in the air,water,soil,food,decaying matter,oil deposits,in plants etc.

but their number and their types vary according to the locality and environmental conditions.

Although, some microbes are always present and contribute towards natural flora BUT besides this others are present in specific environments such as some in hot springs bearing very HIGH TEMPERATURE RANGES for example: <em>Thermus aquaticus.</em>

some of them inhabit the acidic or alkaline soil feeding on HUMUS.

Most of the microbes prefer ATMOSPHERIC GASES i.e some require oxygen for their survival .For example: <em>Pseudomonas.</em>

some don't require O2 for survival i.e <em>Spirochete.</em>

IN SHORT, most of the microbes have preferences for various environmental conditions.

How do enzymes help join two substrate molecules together to form a product?
Len [333]

Answer:

Enzymes bind with chemical reactants called substrates. ... In others, two substrates may come together to create one larger molecule. Two reactants might also enter a reaction, both become modified, and leave the reaction as two products. The enzyme's active site binds to the substrate.

Explain how structure of cell wall in xylem tissue enables it to be strong and flexible?
Drupady [299]
The walls of xylem cells are lignified (strengthened with a substance called lignin ). This allows the xylem to withstand pressure changes as water moves through the plant.

The cell membrane is flexible because of the presence of oil like substances called phospholipids, which gives it a fluid nature. While as the cell walls are rigid because of the presence of the thick layers of the substances like cellulose in plants, chitin in fungi and peptidoglycon in bacteria.
